What's Inside the FOX GRIP2 Damper? FOX Explains

Building off the GRIP's success on the Enduro World Series and World Cup circuits, FOX has added new features and made adjustments to create their most advanced and adjustable damper to date: the GRIP2.

Using the original GRIP architecture as a blueprint, the new damper has been enhanced with new technology: 4-way adjustability, an innovative VVC high-speed rebound circuit, a high-performance mid-valve, and a dramatic reduction in friction.

The GRIP2 damper features moto-inspired FIT sealed cartridge technology combined with a coil-sprung, internal floating piston. Excess oil is purged through a specifically designed port at the top of the damper for consistent damping and increased durability.

To increase durability and performance, GRIP and GRIP2 dampers feature a sealed design with a coil-sprung, internal floating piston. The cartridge body has a specially designed port at the top of the damper to purge excess oil and pressure.

FOX’s previous top-level damper offered high- and low-speed compression and rebound damping. GRIP2 allows for adjustable high-speed rebound using an innovative design called Variable Valve Control, or VVC.

VVC doesn’t just add another adjustment, it offers a significant performance advantage over traditional high-speed damping designs. This caters to a wider range of rider types with better bump recovery, excellent transitions during repetitive hits, and an amazing adjustment range.

One of the key innovations inside the GRIP2 damper is the VVC high-speed rebound circuit shown in blue.

The magic behind VVC is the leaf spring design. Working in conjunction with a traditional shim stack, the high-speed rebound adjuster changes the leverage points on the leaf spring. This not only regulates the high-speed rebound damping but effectively changes valve stiffness, improving damping performance with faster recovery during multiple hits and allowing the fork to ride higher in the travel for a more compliant feel.

Highlighted in blue, the leaf spring controls the high-speed rebound damping by regulating the pressure on the high-speed shim stack.

The leaf spring rides on raised helical ribs designed into the high-speed rebound adjuster plate. Turning the high-speed rebound adjuster changes the fulcrum points on the leaf spring, which increases or decreases the oil pressure needed to open the high-speed rebound shims.

On the compression side, a sophisticated mid-valve design allows more effective shaping of the compression damping curve, offering confidence-inspiring support to combat brake dive and increase cornering stability.

The development of GRIP2 allowed for additional engineering improvements, including updated low-friction seals that help improve small bump compliance and honed, polished, and coated shaft and tube surfaces to further eliminate friction for an unmatched riding experience. 

Whether you’re racing the Enduro World Series, World Cups, or just looking for the best possible ride, FOX’s GRIP2 damper has the performance and adjustability to dial in your suspension.

Available in Factory and Performance Elite 36 and 40 forks, GRIP2 features 4-way adjustability that complements the X2 high-performance shocks, allowing riders to match the front and rear end feel.
